What are the specific policies of the country for contracting barren mountain afforestation?

According to the provisions of the "Guarantee Law", only the land use rights of the "four wilds" are allowed to be mortgaged, and the mortgage is not allowed on the collective land use rights such as cultivated land, homesteads, self-reserved land, and self-retained mountains. I wonder if the land you are talking about is within the scope of the "four wildernesses" (barren mountains, barren ditches, barren hills, and barren beaches)?

Our questions are meant to help others solve problems quickly, not to show our expertise (in fact, the following things don't seem to be your own).

Article 49 of the Rural Land Contracting Law of the People's Republic of China Where rural land is contracted through bidding, auction, public consultation, etc., and certificates such as land contracting and management rights certificates or forest rights certificates are obtained through registration in accordance with law, the land contracting and management rights may be transferred, leased, shared, mortgaged or otherwise transferred in accordance with law. Doesn't the land mentioned in this article refer to the "four wildernesses"? It is said that the "four wildernesses" can be mortgaged.

The following paraphrase is a strong argument for this article, demonstrating why the "four wildernesses" can be circulated by mortgage and other means.
